I get more and more random gray hairs on the crown of my head even though I'm in my twenties, and it's not embarassing, but enough to bug me. I ususually just pluck the few out with a tweezer, but I hear theres these brushes like mascara for your hair? like at Avon or something...Can someone tell me what that's about please? Any advice would help. Thanks!

I have a few stray grays, but I don't really mind them. I henndigo so that pretty much handles them but before henndigo I just left them be. I'm sure once I start getting more and more, I'll continue to henndigo.
